CO Lewis Structure Before we begin,can you tell me how many valence electrons does C and O atom have? How Many TOTAL Electrons Does The Ion Mg2+ Have? So you have 3 bonding pairs surrounding the carbon. Part B. Rameshwar. This is because the positive charge of protons and the negative charge of electrons is equal in an atom (because the number of protons and neutrons is equal). Method 2: The valence electron of the carbon can be determined using a Periodic Table. b. 3- indicates we have a negative charge, and three more electrons than protons. When in an ion state of Be2+ it loses the electrons in a 2s shell and has a configuration of 1s2.
